Place the almonds into a food processor and process them until they are finely ground.

Add vanilla extract and the powdered sugar to the almonds. Knead in the egg whites a small amount at a time until the ingredients are mixed and the dough is smooth and pliable.

Divide the dough in two parts. Add the brandy or rum (I used 1 tablespoon) until you get the desired taste in one of the dough, leave the other without alcohol. Roll the rum flavored marzipan balls in cocoa powder and the plain ones in sugar or chocolate streussel.
